cdrtools (formerly cdrecord) creates home-burned CDs/DVDs with a CDR/CDRW/DVD/BluRay recorder. It works as a burn engine for several applications. It supports CD/DVD/BD recorders from many different vendors; all SCSI-3/mmc- and
ATAPI/mmc-compliant drives should also work. Supported features include IDE/ATAPI, parallel port, and SCSI drives; audio CDs, data CDs, and mixed CDs; full multi-session support; CD-RWs, DVD-R/-RW, DVD+R/+RW, BD-R/BD-RE;
and TAO, DAO, RAW, and human-readable error messages. cdrtools includes remote SCSI support and can access local or remote CD/DVD/BD writers.

For users on Linux and Unix, KDE offers a full suite of user workspace applications which allow interaction with these operating systems in a modern, graphical user interface. This includes Plasma Desktop, KDE's innovative and powerful desktop interface. Other workspace applications are included to aid with system configuration, running programs, or interacting with hardware devices. While the fully integrated KDE Workspaces are only available on Linux and Unix, some of these features are available on other platforms. In addition to the workspace, KDE produces a number of key applications such as the Konqueror Web browser, Dolphin file manager, and Kontact, the comprehensive personal information management suite. The list of applications includes many others, including those for education, multimedia, office productivity, networking, games, and much more. Most applications are available on all platforms supported by the KDE Development. KDE also brings to the forefront many innovations for application developers. An entire infrastructure has been designed and implemented to help programmers create robust and comprehensive applications in the most efficient manner, eliminating the complexity and tediousness of creating highly functional applications.

Zero Install is a decentralized cross-distribution software installation system. It allows software developers to publish programs directly from their own Web sites, while supporting features familiar from centralized distribution repositories such as shared libraries, automatic updates, and digital signatures. It is intended to complement, rather than replace, the operating system's package management. 0install packages never interfere with those provided by the distribution.

rsync is a replacement for rcp (and scp) that has many more features. It uses the "rsync algorithm" which provides a very fast method for remote files into sync. It does this by sending just the differences in the files across the link, without requiring that both sets of files are present at one of the ends of the link beforehand.

CheckInstall keeps track of all files installed by
a "make install" or equivalent, creates a
Slackware, RPM, or Debian package with those
files, and adds it to the installed packages
database, allowing for easy package removal or
distribution.

mkisofs is used for premastering iso9660 filesystems which are used on CDROMs. The output of mkisofs can then be sent to a CDROM writer with a utility such as cdrecord. It has support for many formats, including Rock Ridge, Joliet, and Apple HFS (beta).

SystemRescueCd is a Linux system available from a bootable CDROM
that provides an easy way to perform administrative tasks on your
computer, such as creating and editing the partitions of the hard disk
or backing up data. It contains a lot of system utilities (such as
parted, partimage, and fstools), and basic programs (such as editors,
midnight commander, and network tools). It also includes GParted, a
Partition Magic clone that makes editing partitions easy with its
graphical user interface. This CDROM aims to be very easy to use and
accessible to everybody, and it also provides advanced personalization
features.

BitTorrent is a tool for copying files from one machine to another. FTP punishes sites for being popular. Since all uploading is done from one place, a popular site needs big iron and big bandwidth. With BitTorrent, clients automatically mirror files they download, making the publisher's burden almost nothing.

INSERT (the Inside Security Rescue Toolkit) aims
to be a multi-functional, multi-purpose disaster
recovery and network analysis system. It boots
from a credit card-sized CD-ROM and is basically a
stripped-down version of Knoppix. It features good
hardware detection, fluxbox, emelfm, links-hacked,
ssh, tcpdump, nmap, chntpwd, and much more. It
provides full read-write support for NTFS
partitions (using ntfs-3g), and the ClamAV virus
scanner (including a fairly recent signature
database and a GUI). It provides partition
handling with gParted and also has a network boot
facility.
